Binding the text fields is going to be easier than binding the pop-up menu. There is only one binding you must set for each text field. The value binding specifies what will be displayed in the text field. What is going to be displayed is one of the fields of the currentlySelectedItem variable. For the text field next to the Transport Key label, make the following choices for the value binding:
Bind to: InputController Controller Key: Leave Blank Model Key Path: currentlySelectedItem.transportKey
Binding the other text fields will be similar. The Model Key Path is the only field that will change.
